COTTON-GIN.

SPECIFICATION forming part of Letters Patent No. 244,549, dated July 19, 1881.

Application filed December 31, 1880. (No model.)

To all whom it may concern Be it known that I, DANIEL DEARBORN CLARK, of Mystic, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Cotton- Gins, of which the following is a specification.

The object of my invention is to provide a new device for removing the motes that fall down from the saws of a cotton-gin when-the lint is being brushed ofi' of these saws.

The invention consists in providing a cotton-gin with a mote-receiver, consisting of a longitudinallyflanged cylinder that straightens the cotton as itleaves the saw,knocks the sand and trash out of it, and deposits the motes ina receptacle beneath it, as hereinafter described.

In the accompanying drawings, Figure 1 is a cross sectional elevation of a saw and revolving brush of a cotton-gin provided with my iIDPlOX'd revolving moter. Fig. 2 shows an end and longitudinal elevation of my improved moter. Fig. 3 is an end and longitudinal elevation of a modification ot' the same. Figs. 4. and 5 are end elevations of modifications of the same. Fig. 6 is a side elevation of a modification.

Similar letters of reference indicate corresponding parts.

A cylinder A, having a series of plates, B B, fixed longitudinally and radially in its outer surface, is mounted in the frame of a cottongin or in some other suitable supports below the point of contact of the circular saws C and the revolving brush D. This cylinder is provided with a belt-pulley, so that it will revolve with all the other parts of the gin, or it may be revolved simply by the pressure of the air by the brush.

The cylinder A may be fluted, as shown in Fig. 3, or the plates B may be slightly curved like a scoop, as shown in Fig. 4, or they may be provided with a longitudinal flange, E, at the outer edge, as is shown in Fig. 5. The flutes or grooves F of the cylinder A may be longitudinal, as shown in Fig. 2, or

may be spiral, as shown in Fig. 3, as may be desired. The cylinder may also be constructed with a series of recesses, H, in its cylindrical surface, as shown in Fig. 6.

The operation is very simple and as follows: As the brush D brushes the lint from the teeth of the saws C the motes fall down, and as the cylinder A is directly below the point of contact of the brush and saw the motes will drop into the grooves F Fof the cylinder. As the cylinder A rotates continually, the motes will be carried around and will drop from the groove F in the cylinder into some suitable receptacle. The motes will thus be removed as rapidly as they drop from the lint in a very simple and effective manner.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- In a cotton -gin, the combination, with the saws C and brush D, of alongitudinally-flanged roll, A, having the channels F, arranged to straighten the cotton, knock out the sand and motes, anddeliver said refuse to a receptacle beneath, as described.
